Dr. Marc Ettensohn, MD (UF Chief Resident, Emory ECT Fellow, Published Researcher)
HealingMaps Take: Dr. Ettensohn brings an exceptional academic pedigree to ketamine therapy — Chief Residency at UF, Emory fellowship, and published peer-reviewed research on ketamine’s therapeutic effects. The clinic’s insurance-friendly pricing (Spravato fully covered, ketamine infusions from $250 with insurance) makes treatment more accessible than many competitors. Patients consistently praise Dr. Ettensohn’s kindness and clinical expertise, making this one of the top ketamine clinics in Palm Beach County.
Market Position: Cornerstone Psychiatry Care is a Spravato-certified clinic in the Gardens metro. Spravato (esketamine) is the FDA-approved ketamine treatment that most commercial insurance plans cover after prior authorization — unlike cash-pay IV ketamine.

Patient Questions about Cornerstone Psychiatry Care
This 6-question summary is matched to the protocols and conditions Cornerstone Psychiatry Care treats. Editorial responses are HealingMaps-authored, grounded in our 2026 Ketamine Clinic Intelligence Report.
What ketamine protocols does Cornerstone Psychiatry Care offer?
Cornerstone Psychiatry Care offers Spravato and IV ketamine — a 2-protocol practice. Patients can switch between or combine modalities without changing providers. Confirm specific dosing schedules and which protocols are recommended for your condition during your consult.
Does Cornerstone Psychiatry Care offer Spravato (esketamine)?
Yes — Cornerstone Psychiatry Care offers Spravato, which means they’re FDA REMS-certified and maintain the required two-hour in-office monitoring window after each dose. Spravato is the primary insurance-covered ketamine option for treatment-resistant depression. Worth confirming the prior-authorization timeline before booking your first session.
Is Cornerstone Psychiatry Care suited for treatment-resistant depression?
Cornerstone Psychiatry Care treats depression via Spravato (FDA-approved for TRD), and IV ketamine (off-label, evidence-based). The Spravato pathway is the most likely to obtain commercial insurance coverage. TRD is typically defined as two or more prior antidepressant trials without sufficient response — patients meeting that bar are best candidates here.
Does Cornerstone Psychiatry Care treat chronic pain conditions?
Yes — Cornerstone Psychiatry Care treats chronic pain. They use IV ketamine for pain, which typically means longer infusion times and higher cumulative doses than mental-health protocols. Common indications include complex regional pain syndrome (CRPS), fibromyalgia, and certain neuropathic pain syndromes. Pain pricing varies significantly by structure: per-infusion vs. multi-day inpatient packages — verify how this clinic structures their billing.
Does Cornerstone Psychiatry Care treat PTSD?
Yes — Cornerstone Psychiatry Care treats PTSD. Both Spravato and IV ketamine can be used for trauma. Ketamine for trauma differs from depression treatment: dosing is often lower per session, and pairing the protocol with trauma-focused therapy between sessions is common. A reasonable consult question: whether PTSD patients here typically use ketamine alone or alongside an outside therapist.
Can Cornerstone Psychiatry Care help with anxiety disorders?
Yes — Cornerstone Psychiatry Care treats anxiety, including generalized anxiety, social anxiety, and panic disorder. The evidence base for ketamine in anxiety is less robust than for depression, but it can be a meaningful option for patients who haven’t responded to SSRIs or benzodiazepines. Worth asking which of their protocols they typically recommend for anxiety-primary patients.
